Can You Declare and Initialize Multiple Variables Inside a Go `if` Statement?

Multiple Initializers within Go If Statements

In Go, initializing multiple variables within an if statement is possible, unlike the unsuccessful attempts described in the problem. To clarify, you can initialize multiple variables in a similar fashion to how you would initialize a single variable, using the syntax:

if := , := ; {

// Code to execute if the condition is true

}

This allows you to declare and assign values to multiple variables concurrently, within the scope of the if block. For instance:

package main

import (
    "fmt"
)

func main() {
    if x, y := 5, 38; x == 5 {
        fmt.Printf("Whee! %d\n", y)
    }
}

With this code, when the condition x == 5 is met, two variables, x and y, are initialized to the values 5 and 38, respectively. You can then use these variables within the if block, just as you would with any other initialized variable.
